This development permit to detect duplicate barcodes, stocknumber, and copynumber, when creating items while receiving.
It check in the database, and in the page itself, and prevent receiving if there are duplicate values.
There was work on a duplicate barcode detection feature for creating items while ordering. This feature sounds more complete. Perhaps both can be merged?
This development is already in progress by Julian (Bug 7178)
